Definitions

  • the invention relates to a method for producing a Verpakkungs agreeers, in particular a Germanystube according to the preamble of claim 1.
  • Packaging containers in particular packaging tubes, comprise a tubular tube body, a tube head connected to the tube body, also called a tube tube, with an outlet and an outlet opening and closing cap which engages with the tube head, for example via a thread.
  • Tubular bodies are, for example extruded or coextruded, or produced from a film strip by so-called longitudinal seam welding, in which the edges of the film strip are joined together by application of heat and pressure to form the tube tube.
  • Metals, plastics with and without barrier layers and combinations thereof are used as materials for the tube tubes, with the material selection mostly being oriented to packaged goods for which a tube is intended.
  • High quality packaging such as pharmaceuticals, cosmetics, and other personal care products such as dentifrices containing or acting on gases, require diffusion resistant materials or combinations of materials for tubing, while for undemanding packaged goods such as engineering lubricants, non-barrier materials are sufficient are.
  • Under diffusion is the migration of volatiles understood from the inside of the tube to the outside and vice versa.
  • the latter are equipped with heads.
  • the equipment can be made by compression molding or injection molding or by attaching a prefabricated head to the tube.
  • the plastics used for the heads and pipes are compatible, because in said forms of molding plastics of the head and pipe must flow into each other for the preparation of the compound.
  • one end of the tube is connected to the resulting head.
  • the molding by injection molding is characterized in that a tube tube end is formed during the Formglallvorganges to the head. If a prefabricated head is connected to a tube tube end, then the tube tube is connected by melting and pressure with an edge of the shoulder of a head.
  • the tube tubes are formed largely resistant to diffusion by appropriate choice of material, the adaptation of the diffusion resistance of the tube head to that of the tube tube problems.
  • polyolefins preferably polyethylene (PE) and polypropylene (PP) for Aassemble.
  • PE polyethylene
  • PP polypropylene
  • the material of at least one laminate layer must be used with this head material. ie a cover layer, be compatible so that a head-pipe connection can be made by melting and applying pressure.
  • the polyolefins mentioned have the advantage of good connectivity, but the disadvantage that they absorb volatile constituents, such as, for example, flavorings of packaged goods, with the result that the packaged good loses quality; furthermore, the head may, so to speak, break down by making the material consistency soft, ie spongy. Progressive disintegration of the material consistency promotes the increase in the absorption of volatile components and jeopardizes the strength of the connection of tube head and tube tube. Seals have been developed against this insufficient diffusion resistance. A distinction is made between external and internal seals, the former being applied to cover the outer surface of the tube shoulder, the latter on the inner tube surface facing the tube inner surface, the shoulder surfaces from the neck to the connection of the tube and head.
  • the seals as annular discs, with a central hole as an opening for the spout channel are referred to as rondelles, the place of their application according to as outer and inner rondels.
  • the outer rondels have not acquired the same importance of the inner rondels. This is due to the fact that, in accordance with the design of the material, it impedes or suppresses the passage of gas (O 2 , CO 2, etc.) from the outside to the inside, but is not effective against absorption of gaseous packaged goods components (eg flavorings, etc.), whereas the inner rondels fulfills both sealing functions, provided an inner disk covers the inner surface of a tube shoulder without failure. Defects here are understood to mean wrinkles or corrugations of the roundels whose open sides are not connected to the surface of the tube shoulder. Defects often lead to fractures of the seals, ie Rondellen, whereby any blocking effect is lifted.
  • Plastic-metal laminates consist of an aluminum foil, which is covered on both sides with films made of a polyolefin, ie is covered. Usually, so-called adhesion promoters can be found between the aluminum layer and the polyolefin layers.
  • the aluminum layer or aluminum foil serves as a barrier layer and it provides a barrier layer of very high efficiency against migration of media of any kind, whereas a polyolefin layer serves as a connecting means of the disc with the shoulder surface serving as a covering of the aluminum layer against the packaged material on the polyolefin layer.
  • the advantages of defect-free mounting on the head and the high diffusion resistance are faced with disadvantages of the plastic-metal-laminate rondels. Rondelles are cut out of a material web, ie punched out.
  • Figs. 1 and 2 (the same parts are provided in all figures with the same reference numerals) are shown with 10 only shown in their head end portion tube tubes, which together with the heads generally designated 11 each form part of amaschinestube.
  • the tube tube is formed for example of a three-layer laminate.
  • This laminate consists of a barrier agent layer 12 of EVAL (ethylene-vinyl alcohol copolymer) or PETP (polyethylene terephthalate) both sides planked with layers 13 and 14 of PE (polyethylene), this PE being an LDPE (Low Density Polyethylene) HDPE (High Density Polyethylene), a LLDPE (Linear Low Density Polyethylene) or mixtures thereof may be.
  • the layer 12 may be bonded to the layers 13, 14 by means of interlayers (not shown) of copolymers.
  • one made of metal, preferably aluminum, can also be used.
  • the head 11, also called head part, is formed from a shoulder part 15 and a spout 16 with spout opening 17, the spout 16 carrying on its outer surface engagement means for a tube closure, such as a thread.
  • the plastic head preferably polyethylene, may be either preformed or molded by injection molding.
  • the head 11 can also be formed by pressing a plasticized material portion, ie a blank.
  • the connection of the tube tube 10 and the formation of the head 11 is usually carried out in one step, by injection molding during compression molding Ends of the tube tubes 10 are introduced at one end in injection or compression molding and connected during the molding process of the head with the latter.
  • Spilled or compressed polyethylene has a higher permeability to flavorings and fragrances, oxygen and carbon dioxide than a plastic multilayer film.
  • the head 11 for higher quality Verpackunsgut is diffusion resistant, comparable to seal the tube tube. 1 and 2, for example, in the form of a plate-shaped disc 18 (also called inner rondel) provided on the inside of the tube 11 facing side of the shoulder portion 15 and at one end from the pipe end 19th and the other end extends to the inlet opening of the spout 16 and is preferably connected flat to the head 11. 2 shows an advantageous development of the embodiment according to FIG. 1.
  • the inner disk 18 is designed such that it covers the end of the pipe end 19 introduced into the shoulder part 15 at one end and extends to the inlet opening of the spout 16 at the other end. With this overlap, a better tightness between the inner race 18 and the pipe end 19 is achieved.
  • the Rondelle18 can be glued or welded in accordance with FIGS. 1 and 2 in the tube heads.
  • inner rondels 18 preferably a PE / EVAL or PE / PETP two- or multi-layer laminate, wherein a PE laminate layer 26a the outer surface of the Rondelle, so the surface has to form, which comes after forming the heads 11 by injection or compression molding or assembly with the inner surface of the shoulder 15 of the head 11 into engagement, wherein the EVAL or PETP layer 26 the Barrier against diffusion forms.
  • the plastics of the rondels 18 can be colored. Colored layers facilitate optical quality controls of manual and / or machine type.
  • Plastic monofilms for example PET or PA (polyamide) or EVAL, preferably have a thickness of 15 ⁇ to 80 ⁇ , preferably 20 ⁇ to 40 ⁇ , depending on the contents and tube size.
  • a head 11 In the injection or compression molding of a head 11 are multipart from female die 29 and male (press mandrel) 28 existing tools are used.
  • the head sealing means, ie inner rondels 18, according to the invention with a PE layer 26a are prefabricated applied to the male and during the injection or pressing operation to form the head 11, the PE layer 26 connected to the shoulder 15 in the case of the embodiment of FIG. 2 and with the tube tube 10.
  • the inner PE layer 14 of the tube 10 connect with the outer layer 26 a of the inner rondel 18, which in addition to a greater tightness to an increase in the connection between tube 10th and head 11 leads.
  • the above described preferred embodiment of a method with a rondel 18 is not limited to layers 26a, 26 of polyethylene and EVAL or PETP or PA.
  • designated layers may also include polypropylene (layer 26) with EVAL or PETP, PA, or other barrier-suitable materials (layer 26a).
  • the rondel 18 is a round disc - with a central circular recess 27 - which is provided for the passage of the spout channel forming part 30 of the punch 28 and a recess 27 circumferential circular edge 31, which spans a plane which is perpendicular to the center line of the recess 27, ie the plane and center line are in non-formed state of the rondel 18 to each other at an angle "a" of 90%, ie at right angles.
  • the term "preformed” means any deviation of the angular position from 90 degrees between designated plane and center line.
  • the preforming is expressed below in parts of hundreds, that is, in percent (%) as the degree of preforming.
  • a degree of preforming of zero% means that the designated plane and center line are at right angles to each other.
  • the circular edge 31 of the rondel 18 protrudes from the spout channel forming part 30 of the punch 28, ie from the axial center line at right angles.
  • the punch 28 there is an angle "b" between the center line of the spout passage forming part 30 of the punch 28 and the surface of the punch 32 forming the inner surface of the shoulder 15 of the head 11.
  • a degree of preforming of 100% is when the angle "a" between plane 31 and the vertical center line of the recess 27 of the rondel 18 is the angle "b" (angle of the tube shoulder) between the center line of the spout passage forming part 30 and the surface 32 of the punch 28 corresponds, ie the preformed circular edge 31 rests on the surface 32 of the punch 28.
  • Preforming levels of from 20% (% of the hundred) to 95%, preferably from 40% to 60% are preferred according to the invention. If preforming degrees are less than 20% or more than 95%, it is surprisingly impossible to achieve a secured absence of defects.
  • a shoulder surface 15, in FIG. 2 a shoulder surface 15 and a front connecting end 15a of a tube tube 10 are covered with a roundel 18.
  • Fig. 3b shows a preformed Rondelle 18, the edge 31 as a one-piece edge portion 31a covering a shoulder surface 15.
  • Fig. 3d shows a preformed Rondelle 18 with an edge 31 of two edge portions 31a and 31b, wherein the edge portion 31a, the shoulder surface 15, the edge portion 31b covers the connecting end 15a.
  • the edge part 31a corresponds to the stamp surface 32 (also mandrel surface 32), the edge part 31b of the stamp surface 33, while the stamp surface 33 is at a larger angle to the center line of the part 30 as angle "c".
  • the edge part 31b may have the same degree of preforming as the edge part 31a, whereby, with regard to edge part 31b, the lower limit of the degree of preforming should not fall below 20% and the upper limit of 95% should not be exceeded.
  • the edge portions 31a and 31b have different degrees of preforming, for example at a degree of preforming of 45% of the edge portion 31a (the portion 30 surrounds), the second edge portion 31b (surrounds the first edge portion 31a) Vorformungsgrad of 80% of the degree of preforming of the edge portion 31a.
  • the degree of preforming of the edge portion 31b is to be within a range of 75% to 100% thereof.
  • That of the second partial area may be 37.5% to 50%. It is also expedient to apply the roundels 18 heated to the punch 28 and to move them into the die 29 (FIG. 4) in the heated state, in order subsequently to spray or mold the head 11.
  • An advantageous temperature range is from 40 ° C to 80 ° C, preferred are temperatures of Rondellen 18 in the range of 45 ° C to 60 ° C.
